The larger cube is 20^3 = 8000 cubic cm. So you will need 8000/125 = 64 cubes total. dome7w and 5 more users found this answer helpful.

Answer:
64 cubes
Step-by-step explanation:
Volume of cube with side 20 cm = A³
Where A is the side of the cube
V (1) = (20)³ = 8000 cm³
Volume of cube with side 5 cm = a³
Where a is the side of the cube
V(2) = (5)³ = 125 cm³
Number of cubes needed = V(1) / V(2)
= 8000/125
= 64
